LEE COUNTY, Fla.- A federal judge will decide whether a Cape Coral man can withdraw his guilty plea in a murder for hire plot.

Last fall, 64-year-old Edward McLaughlin pleaded guilty to hiring a Northeastern Pennsylvania man to kill his ex-wife.

McLaughlin says he was persuaded to enter the plea. He goes on to say he was promised the allegations he made against his ex-wife would be investigated.

His attorney says no promise was ever made.
